This invention relates to improvements in means for forming combustible mixtures andparticularly combustible mixtures adapted to be used ininternal. combustion engines and the objects of the invention are to eifect aneconomy in the use of combustible fuel such as gasoline.

A further obiect of the invention 1s to utilize the gasoline tank as a source Of Sl1P.- v ply for the combustion vapours which in accordance with my invention are introduced.

into an internal combustion engine throu h the medium of a carburetor. A further 0 ject of the invention is toprovide a means of forming a combustible mlxture in the gasoline tank to cooperate with the car and increase the .efliciency of the engine.

The invention in the main consists essentially of a gasoline tank having a conductwhich leads from a warm air-chamber connected to the exhaust-manifold while a second conduit is connected to a fuel tank and leads to the intake of the carburetor. Means are also associated with the invention whereby air is introduced into the gasoline tank to provide a form of vaporization within the tank and, in-a ddition to this, agitating means conveniently operated are provided which is designed to provide-further means of vaporizing the combustible fluid within the tank which, as will be hereinafter explained, is directed to the engine forconsumption.

In the accompanying drawings in which like characters of reference indicate corresponding parts,

Figurel is aside elevation partly in section showing the embodiment ofmy invention.

The tank maybe of any convenient wform and, in accordance with the present invention, one side thereof is connected by a.

flexible conduit 10 with the air intake 11 of the carburetor C. The opposite side thereof, as will beseenby-referring to Fi ure 2, has connected thereto a flexible. con uit' 12 leading from a hot air chamber 13' which surrounds the exhaust manifold 14 of the engine B.

.In this particular type of invention it is essential that means be provided whereby I. the fuel within the tank is agitated in such a manneras to create-vapors or fumes which, as will be hereinafter more fully explained,

is directed to the carburetor for consumption in the'engine. The means as shown in the present invention 1s an agltator comprising "afioa't 15 provided with wings 16 vertically slidable and rotatably mounted upon a square or hexagonal shaft '17.

On reference to Figure 3 it will be seen that the shaft 17 extends upwardly into a housing 18 and is provided at the top with a bevel gear 19 meshing 'with a bevel gear 20 which in turn is mounted on a shaft 21. The shaft 21 in turn is connected through a length of flexible shafting 22 to the shaft/23 which is mounted in the exhaust manifold 14 and is provided with a series of propeller blades 24.

The operation of the agitating member 15 will at once become apparent. The spent gas travelling through the exhaust manifold will rotate the blades 24 upon the shaft 23 in turn operating the shaft 17 to cause the Figure 3 is an enlarged transverse section.

terial whereby this member always remains at the level of the fuel within the -tank.'

In addition to the foregoing, a further means of agitating the fuel in'the tank com- W prise the introduction of air thereinto, preferably. from the base hereof. The means which I have shown comprise an air line 25 connected to an convenient type of air compressor 26 whie may be driven through the 0 eration of the engine B and connected to t e base of the tank D as indicated at 27. A

valve 28 within the tank is provided with a ball check 29 by which means air is permitted a flap valve 32. -The valve 31 is designed to.

permit the vaporized fuel to pass from the tank to the carburetor but in the event of back-firing through the carburetor the valve will prevent the back-fire from entering the gasoline tank. As the valve 31" .closes to prevent the back-fire from entering the gasoline tank, the flap valve 32 automatically opens and allows the back-fire to escape to the atmosphere.

In operation the action of the engine will cause air to be forced into the fuel tank by the operation of the pump 26 which will agitate and tend to vaporize the fuel. Simultaneously with this operation'the spent gases of exhaustion will operate the blades on the shaft 23 which in turn will affect the operation of the agitator member 15 which through 5 its rotary movement will create a vapour within the fuel tank. The suction of the engine operating through the carburetor and the intakethereof will simultaneously with the aforementioned operation create a suction 40 in the conduit 10 which will draw off the fuel vapoursor fumes from the upper part of the tank D which have been created therein. During this operation heated air passes from the hot air chamber associated with the exhaust manifold by means of the conduit 12 to the tank D. which will'further assist in the vaporization of the fuel within the tank.

From the foregoing itwill be apparent that novel and effective means are provided the creating of vapours or fumes within the fuel tankfor consumption by the engine.- As-many changes could be made in the above" construction and many .apparently ,my hand.
